Development

To run the local engine server:

bundle install
bundle exec rake doorkeeper:server

By default, it uses the latest Rails version with ActiveRecord. To run the tests with a specific Rails version:

BUNDLE_GEMFILE=gemfiles/rails_6_0.gemfile bundle exec rake

You can also experiment with the changes using bin/console. It uses in-memory SQLite database and default Doorkeeper config, but you can reestablish connection or reconfigure the gem if you need.
